However, F1's commercial managing director Sean Bratches reckons 21 is just the start.

"We want to work in partnership with our teams in terms of determining where we go, but our view is that we’d like to go above 21 (races)," Bratches told Reuters.

"And we want to be a little bit more proactive and go on the offensive in terms of the markets where we go."

He added: "As we start identifying an optimal calendar in optimal regions, we can go down and sit with cities and make our case as opposed to what has been a little bit more reactive to bids coming in."

However, a longer season is likely to put a strain on team personnel while Bratches re-iterated Liberty's desire to avoid conflicts with other major sporting events.

"What we do has to take all that into consideration and we have to work closely with our partners on the team front to find out what the high water mark is and what makes sense for everyone," he said.

"We are very interested in doing what’s best for fans.

"Next year… there is a weekend where the Wimbledon final and World Cup final take place on the same day. It would be sub-optimal to have the British Grand Prix on that day. It’s a tight schedule."
